It's a great release
Much nicer in use because of the footprint, OVF and shutter, and increased usable ISO from 1600 to 6400 over 240. No camera is perfect, still heavy and batteries not great, but all things considered they hit the ball out of the park.
I never heard a M240 user admit to video, so I doubt lack of it will hurt much. Technically a sony r2 BSI sensor could be in this form factor and shoot 4k without overheating. But I don't think that was an option for Leica.
Certainly a small EVF FF L mount with "everything" would be a huge hit, and rumors are flying they have one in the works, or alternately it is not. :lecture:
Whatever, M10 is the new M9. Good job, Leica. :clap:
